Claims (1)
- 【特許請求の範囲】 1. 内燃機関の少なくとも1つの停止されたシリンダの再始動時の燃料噴射付 加量検出方法において、燃料噴射付加量(tewe)を、再始動の時点での負荷依存の 壁膜量(WFM1)と補正ファクタ(fwe)との乗算によって求め、該補正フ ァクタ(fwe)を、エンジンブレーキ遮断状態の間、再始動する迄第1の時定 数(ZFSA)で増加制御し、続いて、前記補正ファクタ(fwe)を第2の時 定数(ZFWE)で再度低減制御することを特徴とする燃料噴射付加量検出方法 。 2. 時定数(ZFSA,ZFWE)は負荷依存及び/又は回転数依存である請 求の範囲第1項記載の方法。 3. エンジンブレーキ遮断状態(B_SA)の発生時に燃料噴射付加量(te we)の低減制御過程の間、前記低減制御過程を遮断して、燃料噴射付加量(t ewe)を値0にセットする請求の範囲第1項記載の方法。
